Now that computer and electronic control systems are widely established, many essential services (such as hospitals, traffic control, airports etc) and industrial / production facilities (including power stations) can be seriously disturbed by breaks in or contamination of their power supplies. This book is a comprehensive guide to the various types of uninterruptible power supply (UPS) available, and how a UPS can be specified and applied for safe and reliable functioning in the working environment.

As industry power demands become increasingly sensitive, power quality distortion becomes a critical issue. The recent increase in nonlinear loads drawing non-sinusoidal currents has seen the introduction of various tools to manage the clean delivery of power. Power demands of medical facilities, data storage and information systems, emergency equipment, etc. require uninterrupted, high quality power. Uninterruptible power supplies (UPS) and active filters provide this delivery. The first to treat these power management tools together in a comprehensive discussion, Uninterruptible Power Supplies and Active Filters compares the similarities of UPS, active filters, and unified power quality conditioners. The book features a description of low-cost and reduced-parts configurations presented for the first time in any publication, along with a presentation of advanced digital controllers. These configurations are vital as industries seek to reduce the cost of power management in their operations. As this field of power management technology continues to grow, industry and academia will come to rely upon the comprehensive treatment found within this book. Industrial engineers in power quality, circuits and devices, and aerospace engineers as well as graduate students will find this a complete and insightful resource for studying and applying the tools of this rapidly developing field.

An important part of any communication system is its power supply system. The smooth operation of all communications depends on the quality of the power supply and on the operational reliability of the increasingly complex equipment and devices used for this purpose. This book describes current power supply technologies, it explains the circuit techniques using easy-to-understand examples and illustrations. Also covered are automatic control, grounding and protection techniques as well as the design of battery and grounding installations. The book is conceived as a practical guide for those involved in planning installing, comissioning and servicing telecommunication systems, but it is also useful as an introduction to the subject.
